Be it" v own at '1, Roman W. JeannnUne, 'a citiien of the German Empire; and a resident renew York, in the county and State o f New York, have invented. certain new and useful Improvements in Machines for-Making Artificial-Stone Shingles, &'c., of which the fqllowingis a-specification.

This invention has reference to improvements inmachinefor makin artificial stone shingles, plates',% slabs. and t elike from a composition oflasbestos or other fireproofmaterials which are thoroughly and uni forinly mixed with hydraulic cement andanhydrous silicon dioxld and some water.-

Itjs thespecial purpose of thepresent inventlon to produce a machine for making artificial ,stone shingles in one continuous operation. The mixed mass, in a'eplastic condition is allowed to flow ,from the mixer by gravity down into measuring devices whic are automatically opened and iclosed hythe rotation of the machine. Fromqthe mass is filling the same. There arefurthcr devices for equalizing the compressed air pressure on the surface of each measured:

measuring devices the measured quantitie's pass down into the shingle forming device wherein air pressure is a plied to squeeze. out the water and form tie shingles, slabs or plates. An endless beltdevice isiprovided'which is automatically and intermib. tentlyraised and lowered bycam arrangements so as to receive the pressed or formed shingles and transport them outof the ma.- chine. i

Means are provided within the machine to produce plates of uniform thickness or shingles having'a slanting surface whileheing rectangular at the opposite side. These shingles with slanting surface reduce what architects tcrni a beautiful 5 adow eflect.

Such tapered artificial roofing" material'is easier laidxand nailed and more desirable than artificial shingles of uniform thickness.

In addition to-thesemain objects means;

areprovid'ed on the measuringjdeviiies' to allow o the escape ofair while the plastic quantity of plastiofmass within the shingle molding device."

All the described valves are ,antomatifcally. opened and closedby means of special devices. Each device comprises-a short lever arm Z, 1 ,1, one'each," connected with an inlet valve.

The extension of each e air pressure valve opens discharge valves the discharge valve reaches into the pressure box 41... In the upper section 'of the pressure box an air deflecting plate w is provided for the; purpose of checking the in: rushing air from the air distributing it uniformly.

This connectswlth an eccentric-10 mounted upon UV indicated in Fig. 4 whereby grate, screen and. belt are raised and pressed against the bottom of the pressure box. The. box 8 when moved up and down inc plane ened and closed.

mass has left the measuring measuring tubeb e pressure tube and extensions of the measure molding frame so as to retain the plastic a mass therein and mold the shingles or plates,

fabric adapted plastic mass to pass through when the compressed air pressure is applied to said mass. The belt runs A from the is guided in.v

the upper portion of the frame 13. The. be

screen and the section ofythe belt there-,- on are pressed againstthe molding frame of whereby taperedshingles result. As shown in Fig. 1, the gratejwith screen thereon is secured to a hinge 11 on 'one side and a set screw 12' is provided on the other side Whereby' the machine may be adjusted. In this wayplates of uniform thickness may be producedwith this machine as well. as tapered shingles. The device shown in Fig. 4, however i stationary for'the production of one style of plates or shingles-u In this modified form a perforated disk w is shown in place of the air deflector w to equalize the air pressure.

The endless belt is tensioned by means 'of springs 14 of which one is-shown in Fig. 1. In order to transmit the motion of the main shaft to the belt a gearwheel" 15 ismounted on the main shaft enga in .a gear wheel 16 ou aseparate shaft-1, pon this shaft there is mounted a Geneva wheel 18 with a stop pin 19 to produce'the, intermittent movements described.v The gear wheel 16 actuates a bevel gear 20 on a shaft 21 which in turn actuates a'bevel'gear 22 upon a shaft 23. This shaft is mounted in bearings upon the frame 24. .The shaft 23 supports the roller 3-over which the belt passes. suming that the main shaft rotates then {the eccentric 0 opens the iniet valves of the ,fi-n'easuring devices and closes the discharge .i'alves of .the same, Now the measuring tube is filled and upon further rotation of the eccentric 9 theIinl-et valves are closed and the discharge valves opened permitting tlre contents to flou down into the space underneath the airdefl-ectorw of the pres sure box Properlytimed therewith-by thegearwvheels'anc'l Geneva Wheel with stop 'pin andthe bevelgeaa's the eccentric '10 box to retain the contents of the measuring w in the sections of the said frame. Now the air pressure valve t. is automatically opened and the compressed air passes" through, the tube uontothe air deflector 41: into the air chamber w-. The compressed air us is uniformly, distributed. If a perforated disk w is employed the. air passes through its perforations-intoitheyair;chain 'b'er m,- The-air presses theiwater out'ofthe plastic mass through the fabric of which the endless belt. .is composed thereby forming the shingles or plates in the molding sections of the molding frame. When the air valve is open' the discharge valves of the measurf ing devices are :clos I and the inlet valves open. :By the continued rotationof the 7 main shaft the eccentric 10' descends with thescreen and the section of the h 'mo belt transports the molded.
